Northwest Coastal

Conditions are generally safe, but keep in mind small, isolated avalanches are still possible with low hazard.

Continue to assess your route carefully and follow safe travel practices.

No new avalanches have been reported. Last Friday and Thursday, north of Stewart, several explosive and rider-triggered wind slab avalanches occurred up to size 1.5.

Wind slabs like these are becoming less likely to trigger, but may remain sensitive to human triggers in isolated areas, particularly where they overlay surface hoar.

On the surface, around 15 to 30 cm of snow has combined over the last two storms. At higher elevations, this snow is likely heavily wind-affected and rests on a thick rain crust. In some areas around Terrace and Stewart, it may also be overlying weak surface hoar or facets.

Recent strong winds have varied in direction, so wind slabs may be present on all aspects. These slabs should bond quickly, but may be more reactive where they overlie the weak surface hoar and facets.

The mid and lower snowpack are not concerning at this time, and are made up of various hard layers, or moist snow at lower elevations.

• Carefully evaluate steep lines for wind slabs.
• Wind slabs are isolated, but may remain reactive.
